What are the different types of rocks? Sedimentary Rocks Igneous Rocks Metamorphic Rocks Click here to find out!

Sedimentary Rocks Sandstone  Sedimentary rocks are little pieces of our earth that have been washed and worn away by wind and water for thousands and millions of years.  Have layered appearance because the materials that form them are deposited in layers.  Sedimentary rocks that are compacted contain rock particles such as pebbles and sand. Limestone Gypsum

Igneous Rocks  Igneous rocks are also called “fire rocks” and are formed either underground or above ground.  Some igneous rocks erupt from volcanoes as lava or pumice.  Others, like granite, form underground magma chambers.  Fine-grained igneous rocks include Basalt.  Volcanoes  Obsidian Rocks  Pumice Rocks Click before each of the names to learn more about them!

Metamorphic Rocks  Metamorphic is Greek for “change of form.  Are rocks that have “morphed” into a different type of rock.  These rocks were once igneous or sedimentary rocks.  Have a banded or layered appearance.  Metamorphic rocks are hard and strong. Gneiss Schist Click me!

Fossils  Fossils are the only remains of ancient animals and plants, traces or impressions of living things from the past geologic ages.  Fossils have been found on every continent on Earth.  The only direct way we have of learning about dinosaurs is by studying fossils. Plant and animal fossils can be found in many sedimentary rocks. Click on the dinosaur to find out how! Click me!

Objectives Students will explore the 3 main rock types. o Sedimentary o Igneous o Metamorphic Students will learn how each of the different rocks are formed and will examine a few examples of each. Students will learn about fossils, how they are formed, and how they are connected to past life forms.
